I agree. I think the Silver Cov would be the logical ‘Go to’ even though I know they are just one -group- of High Elves, they are probably, in fact almost certainly, the most iconic. They actually did something similar with the Belf Heritage set, it comes with a robe or a trousers option, I just happened not to like either, so used the shoulders, gauntlets and cloak, and the rest is the Legion Hunter PvP stuff, which by happy coincidence, really matches.
I think that is definitely the way forward with Heritage sets though, making a caster/melee option,
I think Silver Covenant would look pretty good, but as I say, instead of the Blood Elf angle to the Pauldrons, with it being an eagle head instead, the reason I reckon that is more to do with the fact that the whole ‘Phoenix rising again’ thing is much more a Blood Elf Motif, whereas the Silver Cov look would be ‘Old Skool’ Thalassian chic, as it were.
Aside from that, the armours are going to look pretty similar, Its a shame there isn’t a proper blue set that really works, for those trying to RP as High Elves using the Void Elf Model, although the ‘Rift Stalker’ set (I think it is) actually works pretty well… Well, apart from the helmet and shoulders…
There was a guild on AD “The Silver Sun” who played High Elves, but on Horde side, and I think they used that armour set, which looked pretty good, but then, that comes with the attendant problem of it only being wearable by certain classes…
